The 2017 Memorial Cup, which begins Friday in Windsor, Ontario, is a paradise for junior hockey fans and scouts alike -- an annual 10-day tournament that pits three Canadian Hockey League champions against a host squad, all vying to be crowned the best team in Canada. While keeping an eye on draft-eligible players, the Blackhawks will also monitor the progress of their four prospects taking part in the tournament this year, all of whom are under contract, a rarity for the club. Highlighted by 2016 second-round pick Alex DeBrincat, the team's three representatives are competing for three of the four teams in contention.
